    The increasing use of the Internet for business compels everyone to consider setting up a Web site as soon as possible. Creating your own Web site is not as expensive or as difficult as you might think. The following describes an efficient and economical way to get on the Web-fast. After you have claimed your spot on the info highway, you can deliberate and later add complex options that most likely will require professional help View full abstract»

    The development of optical interconnect technology using fiber optics in the 1970s was a cornerstone of the modern telecommunication industry. Replacing copper cables with optical fibers provides superior performance in terms of wide data bandwidths, reduced noise, and low loss. It also significantly reduces the cost of communication in terms of dollars/bit/km. Optical interconnects not only provided the infrastructure critical to the explosive, growth of telecommunication that followed, but also paved the way for the information industry to flourish today View full abstract»

  • A/D and D/A conversion for telecommunication

    Emerging telecom systems such as ADSL and VDSL demand state-of-the-art high speed and high resolution analog-to-digital converters (ADCs) and digital-to-analog converters (DBCs). Moreover, cost and power consumption issues require the use of specific A/D and D/A architectures to achieve the wanted resolution at the required speed at minimum power. In the first part of this article we present an overview of the various ADC and DAC architectures used in Alcatel Telecom systems over the past 15 years, with an emphasis placed on the evolution of ADCs and DACs for today's asymmetrical-digital-subscriber-loop (ADSL) applications. We then discuss design considerations for high-speed and high resolution ADCs for future very-high-data-rate digital subscriber-line (VDSL) technology View full abstract»

  • Going mobile [mobile-computing networks]

    Discusses virtual versus physical process-migration strategies in modeling mobile-computing networks. Both VPM and PPM play useful and effective roles in the modeling and simulation of real-world, mobile-computing networks. While PPM is a more accurate model of reality, by its very nature, VPM helps realize the modeling of networks with large numbers of mobile entities on testbeds with a modest number of processors, although at greatly reduced performance. Utamaphethai and Ghosh [1998] reported a TVHS simulation with 45,000 entities representing autonomous vehicles on a network of 60+ SUN Sparc 10 workstations. In contrast, a PPM implementation would be difficult to realize due to the large number of processors required and it would be unacceptably slow due to the large numbers of connections and disconnections. PPM is unquestionably superior when the computational loads associated with the mobile entities are high. However, its performance suffers relative to VPM where the system demands intense data exchange between the mobile and stationary units. This study also underscores that, for scalability in performance, the algorithms underlying real-world mobile computing networks must be designed to reduce communication while increasing local computation View full abstract»
